My 90 year old Mom seems to have no energy, won't stand straight, and her voice became deep with effort to talk it seems. She is fairly healthy, controlled high bp, no other issues... any idea of what might help? I know there is some circumstance I read about a number of years ago where a man started to shuffle-walk and it was discovered he had something that was "fixable"....... I know this is vague , just curious about some ideas. I no longer accept that it "just old age".... thanks, ct
